The BeMicro CV (originally) shipped with no design files. We try to compensate here with a collection of useful examples. Note, the LED pin assignment given in the documentation is wrong and corrected in these designs.
The first ```led_and_serial`` is the typical first Does-It-Work kind of design which runs a counter on the LEDs.
This also adds a small serial (RS232) input/output engine:
-
TX is on GPIO 1, that is J1 pin 1
-
RX is on GPIO 2, that is J1 pin 2
-
Speed set to 115200 bps
To use connect a USB BUB (or similar), RX to J1-1, TX to J1-2 and ensure that it's configured for 3.3 V signaling.
The second nios_ddr3
comes curtesy of Guy Lemieux

and illustrates how to instantiate the
DDR3 controller and a NIOS II example.
Suggestions and contributions welcome.
